The modified Poisson regression and three machine learning algorithms including eXtreme Gradient Boosting, support vector machine and random forest were used to develop prediction models.

A total of 13 important predictors were selected to develop the model, including age, education, contact with their children, medical insurance, vision impairment, heart diseases, medication types, self\u2010rated health, pain locations, loneliness, self\u2010medication, night\u2010time sleep and having running water. All models showed acceptable or approximately acceptable discrimination (AUC 0.683\u20130.809) for the training set, but fair discrimination (AUC 0.568\u20130.666) for the internal and external validation. For calibration, only modified Poisson regression and eXtreme Gradient Boosting were acceptable in the training set. All models had acceptable overall prediction performance and clinical usefulness. Older adults were divided into three groups by the risk scoring tool constructed based on modified Poisson regression: low risk (\u226424), median risk (24\u201329) and high risk (&gt;29).<\/jats:p>\n
